What “certh” means
WikipediaThe Cirth is a semi‑artificial script, based on real‑life runic alphabets, one of several scripts invented by J. R. R. Tolkien for the constructed languages he devised and used in his works. Cirth is written with a capital letter when referring to the writing system; the letters themselves can be called cirth.
